Batteries
1 Fully charged and otherwise satisfactory batteries must always be used when working on the electrical system.
2 Test the batteries with an acid tester. The battery disconnect switch should be turned off.
3 When installing a battery, make sure that the battery is con‐nected with the correct polarity.
4 When changing batteries connected in series, make sure they are of equal capacity, for example, 2 batteries of 105 Ah. The batteries should have the same age (same quality), since the charging current required to reach a certain voltage varies with the battery's age.
5 If booster battery is required when starting, the following instructions must be followed at all times; 191, Safety when working with batteries and 191, Starting with booster batter‐ies
Charging
1 Before performing any tests of the alternator or regulator, the batteries must be checked regarding insulation, loose fit, and corrosion. Check the alternator belts.
2 For all testing of alternating current equipment, use “secure” connections in order to prevent sparks and voltage transients. A loose cable may result in destruction of both the alternator and regulator.
3 Never disconnect the alternator leads while the engine is run‐ning. This could damage both the alternator and regulator.
4 If the current alternator output socket should be connected to the chassis, damage may occur to the alternator and regulator.
Components
When removing or installing components in the electrical system, turn off the voltage supply with the battery disconnector.
Welding

4 Climate control unit ECC (MID146)
5 Instrument control unit I-ECU (MID140)
The machine electronics contain five control units that communi‐cate with each other via two data buses. Each control unit pro‐cesses values from sensors and operating controls, and controls components so that desired function is obtained.
Control units included in the system are the instrument control unit I-ECU, vehicle control unit V-ECU, vehicle control unit V2ECU, engine control unit E-ECU, and climate control unit ECC.
Machine electronics facilitate troubleshooting with a welldesigned and expansive diagnostic system. In case of electrical malfunctions/errors, the operator receives a message on the information panel.
For service personnel, the service tool VCADS Pro can be plugged into sockets located by the electrical distribution box behind the operator's seat.
Instrument control unit I-ECU is located in the instrument panel and contains software for presenting operator information on the information panel, including warning and control lights. The con‐trol unit receives information from the other control units via data bus.
Engine control unit E-ECU is located on intermediate wall in the engine compartment and contains software for controlling engine functions. The control unit receives information from the engine's own sensors as well as from a data bus. The control unit also sends information to the other control units via data bus.
Vehicle control units V-ECU and V2-ECU are located by the elec‐trical distribution box behind the operator's seat and contains software for controlling components and handling information from sensors located outside the cab. The vehicle control unit is connected to the other control units via data bus.
Climate control unit ECC are located inside the right side panel in the cab and contain software for controlling heating, cooling, and ventilation. The climate control unit is connected to the other con‐trol units via data bus.
Communicationfor programming, changing parameters, and reading out error codes, testing and checking components, etc. is done with VCADS Pro. In VCADS Pro, MID-designations (Mes‐sage Identification Description) are used for the control units. Reading of input and output signals, setting certain functions, reading off machine information, etc. can be performed with the information panel.

General
In principle, the machine electronics are based on all communi‐cation between control units in the system taking place via two data buses. The machine's control units are connected to the buses to enable communication with each other.
Communication between the different control units as well as reporting from control units to service sockets takes place on data buses CAN1/J1939 and J1587/1708.
The buses follow SAE standards and consist of two pair-twisted cables. The purpose of the twisted cabling is to protect the bus from electrical interference.
If an error or malfunction should occur in any system, a signal is sent out on the information bus which makes it possible to read off the information either in the information display or with VCADS Pro. In VCADS Pro, MID-designations (Message Identification Description) are used for the control units.
The figure above shows the principle for how the control units and service sockets are connected to the buses.
V1047172
CAN1/J1939 control bus
System control signals are sent via this bus. The control bus is very quick, which is necessary for control of the entire system to work and quickly adapt to changing conditions.
The main communication alternative is the CAN1/J1939-bus. However, for E-ECU, some control data is only sent on the J1587/ J1708-bus.
CAN2/J1939 control bus
CAN2/J1939 is used to obtain redundancy for CAN-communica‐tion.
J1587/1708 information bus
The information bus is connected to the control units and service socket. Information and diagnostic signals are sent on this bus. In addition, some control data is sent from the engine control unit via this bus.
The bus also acts as a “back-up” for the control bus if it does not work for some reason. The system's status is continuously updated and available for reading via the information bus.
By connecting VCADS Pro to service socket VP, it is possible to read error codes, perform test, delete logged information, down‐load parameters, and download software.
Software, description
Regarding: L60F, L70F, L90F
Software is stored in the control units. To determine which soft‐ware is in the control units, the part number of the software (Main software) is read in the information panel or with the service tool VCADS Pro.
Updating of the machine's software is handled through release of a new edition. The releases are designated with Year:edition, for example, R2006:5 and gets a new part number.
Updating of software for control units takes place through down‐loading of new software from VOLVO with VCADS Pro.
